Size Optimization of a Weight-Balanced Haptic Device

Abstract:

A size optimization is performed to a weight-balanced haptic device. Firstly design requirements for mechanical parts of haptic devices are summarized. After analyzing factors influencing force-reflecting accuracy, a basic idea is got that the device should be weight-balanced and should have minimum apparent mass while keeping certain stiffness. Then a simplified model is got for the prototype and apparent mass and stiffness is analyzed and expressed in terms of variables based on the simplified model. With link cross section set to be circular tubes, an optimization is done to find link diameters and wall thicknesses with lowest apparent mass and given stiffness. At last the optimization result is analyzed and the model is proved to be reasonable.
